Tool for fixation of cable or line

ABSTRACT

A tool for the fixation of a cable or line on a support by adherence means, the tool comprising a pressure wheel for guiding movement on and along said cable or line when mounted on a handle. The circumference of the pressure wheel is adapted to the form and dimensions of the cable or line in such a way that a predetermined pressure for adhesive fixation is applied with said guided movement. The circumference of the pressure wheel suitably comprises a cylindric groove track delimited on each side by a flange for contact against the support when applying pressure for adhesive fixation during the guided movement on and along the cable or line. The circumference of the pressure wheel may also comprise a frustoconically shaped groove track delimited at its narrower side by a flange to be in contact with the support and at its wider side by a transverse surface to be supported against a wall surface during the application of pressure for adhesive fixation during the guided movement on and along the cable or line. Preferably the tool is implemented for exchange of the pressure wheel in order to adapt different pressure wheels to different lines and cables.

The present invention relates to a tool for the fixation of a cable or aline on a support.

Lately it has been developed many new types of cables and lines both forpower supply and information transmission. Oval and flat cable typeshaving varying external diameters and being implemented with new typesof materials both as to insulation and conductors (e.g. lightconductors) as well as lower weight, have appeared in a addition to thetraditional types. Also, new quality standards before and after mountinghave lately been introduced.

Traditional tools for the fixation of cable and line are apt to causedamage on the protective coating or squize together the isolationmaterials between the conductors, as great force must be applied to theimpact tool for fixation of the retaining means to the support. Also,the supports for fixation may comprise different and newer types ofmaterial than earlier. On this background new fixation means has beendeveloped, as for instant staples, castor clamps, adhesives on thesupport or the cable/line, or adhesive tapes.

In German patent No. 827 372 issued to Dr.Ing. Alfred Bush in 1952 it isdescribed a tool for preliminary fixation of cable or line with appliedadhesive as fixation means. This tool is, however, purely a guidancetool for guiding the cable from a cable drum to the fixation supportbefore the cable is stapled in cable channels or cable buffers. The toolis provided with a guide wheel which has a half-rounded groove for thecable in the center and guide tracks on both sides. Further, the toolcomprises a grip handle, on which the guide wheel is mounted by means ofa through bolt in a holding fork and locked by means of a pair ofsplints through the wheel shaft. The central groove of the guide wheelare also centered against the cable drum, which make the guide wheeldependant of the motional parth of the drum. The pressure applied by theguide wheel to the line or cable in question is dependant of theobliqueness of the handle, and in order to achieve the requiredpressure, it would be necessary to grip the handle with both hands.

The tool according to said German patent is developed only for cabletypes having a sheath of iron or other metals. This tool is hardlysuitable for the mounting of cables or lines of modern types.

It is then an object of the present invention to provide an improvedtool for the fixation of a cable or a line to a support by means ofadhesive, said tool being well suited for use on lines and cables ofmodern types in order to achieve permanent mounting of these.

Thus, the invention is related to a tool for fixation of cable or lineon a support by means of adhesive, the tool comprising a pressure wheelfor guided movement on and along said cable or line when mounted on ahandle.

On this background of prior art, the characterizing feature of the toolaccording to the invention is that the circumference of the pressurewheel is adapted to the form and dimensions of the cable and line insuch a way that a predetermined pressure for adhesive fixation isapplied with that guided movement.

For adhesive fixation of the cable or line on a free horizontal orvertical support, the circumference of the pressure wheel comprises acylindric groove track 11 delimited by flanges to be in contact with thesupport when applying pressure for adhesive fixation.

For fixation of a line or a cable along a wall corner, the circumferenceof the pressure wheel preferably comprises a frustoconically shapedgroove track 10 delimited at its narrower side by a flange to be incontact with the support, and at its wider side by a transverse surfaceto be supported against a wall surface during the application ofpressure for adhesive fixation.

Preferably the tool is implemented in such a way that the pressure wheelis exchangeable, in order that the tool may be used for mounting ofvarious lines or cables having different form and dimensions byutilizing different available pressure wheels. The pressure wheel isthen suitably adapted to be connected with an anchor pin having anassociated snap lock at one end, the handle being provided with aninternally threaded fixation hole for the insertion of a screw for thesnap lock.

The tool according to the invention will now be described in moredetails with reference to the accompanying drawing, on which:

FIG. 1 shows the tool seen obliquely from the side,

FIG. 2 shows the tool handle seen from the front side with the pressurewheel removed, and

FIG. 3 shows the pressure wheel demounted from the handle.

As shown in FIG. 2 the pressure wheel 1 is mounted on the tool handle 2by means of an anchor pin 3. The anchor pin 3 is maintained on thehandle by means of a snap lock 4, the handle 2 being provided with athreaded hole 5 for receiving the snap lock screw 4. For receiving thepressure wheel the tool handle 2 is provided with a guide spindle 6 witha bore 7 for guiding the anchor pin 3 to the snap lock 4, at which theanchor pin 3 is shaped with a round-threaded groove at the snap end forengaging the snap screw 4.

Further, the tool handle 2 is provided with fixation grooves forengaging an extension rod. Also, the handle is produced with an impactsurface 9 for impact tools, and formed with a convex curve 12 taperingtowards the handle end for the mounting of the pressure wheel 1.

As shown in FIG. 3, the circumference of the pressure wheel 1 is formedwith a cylindric groove track 11 delimited on both sides by a flange tobe in contact with the support when pressure is to be applied on a linefor adhesive fixation. Furthermore the pressure wheel 1 is also providedwith a frustoconically shaped groove track 10, which at its narrower endis delimited by a flange to be in contact with the support and at itswider end by a transverse surface to be supported against a wallsurface, when pressure is to be applied to a line for adhesive fixationalong a wall corner.

In case a line is to be adhered to the support by means of a toolaccording to the invention, adhesive is first applied to the line and/orthe support. Thereafter the line is placed with adherent contact againstthe support, and a correspondingly adapted groove track 10 or 11 on thepressure wheel 1 of the tool is pressed against and guided along theline to achieve a secure adhesive fixation on the support.

With a preferred embodiment a suitable double sided adhesive tape isfirst applied to the support at the mounting area. After removing thecover sheet at the top side of the adhesive tape, said line or cable isplaced at the uncovered adhesive surface and pressed against the samefor good adhesive fixation by means of the tool according to theinvention, as described above.
